SAFE.

SPECIFICATION forming part of Letters Patent No. 587,028, dated July 27, 1897.

Application filed October 25, 1894;. Serial No. 526,922. (No model.)

To (LZZ whom it may concern.-

Be it known that I, LEVI D. YORK, of Ports mouth, in the county of Soioto and State of Ohio, have invented a certain new and useful Improvement in Safes of which the following is a specification.

My invention relates to safes of the kind which are made up of an interior and an eX- terior shell secured one to the other by suitable means, preferablyby shrinking the same together by the aid of heat to form a rivetless and boltless structure throughout.

My present invention relates particularly to safes embodying an inner and an outer shell, both sectional in their character, or, in other words, comprising a series of rings placed end to end, which are provided with engaging devices and are adapted to be locked together by the aid of heat and one of which is provided with means for interlocking all the remaining rings.

I will describe a safe embodying my improvements, and then point out the novel features in the claim.

Figure 1 is a front view of a safe embodying my improvement. Fig. 2 is a transverse section of the same on the line 2 2 of Fig. 3. Fig. 3 is a longitudinal sectional elevation taken on the line 3 3 of Fig. 1. Fig. 4 is a longitudinal sectional elevation of a modification.

Siniilar letters of reference designate corresponding parts in all the figures.

A designates an inner shell, preferably cylindrical in form, whose interior surface forms the bore of the safe.

13 designates an outer shell surrounding and rigidly secured to the inner shell. Both the inner and the outer shells are made in sections, each section consisting of a ring or annulus. Of course the sections of the inner shell will. break joints with those of the outer.

In Fig. 3 I have shown the outer shell as comprising three annuli B B B placed end to end. Similarly the inner shell is made up of two annuli A A. Not only will the inner and outer shells preferably interlock with each other, but the separate sections comprising the inner shell or those comprising the outer shell will interlock one with the other.

In securing the inner and outer shells, as

well as the sections comprising the separate shells, together I make use of a shrink-fit secured by the aid of heat. Consequently the relative diameters of the two shells and their interlocking parts must be suited one to the other to permit of this.

I have represented an advantageous configuration of the separate members forming the safe adapted to the securing of one member to the other.

Referring to Fig. 3, the inner annuli A A abut one against the other. The annulus A is provided with an outer annular groove or recess a having shoulders or a at opposite ends. Similarly the annulus A is provided with an outer annular groove or recess a with shoulders (t a at the ends. The outer annuli B B are provided with the respective shoulders I) b to engage with the corresponding shoulders of the inner annuli A A The outer intermediate annulus B serves in this instance the purpose of looking all these parts together. To this end it is provided with annular flanges or tenons Z) N, which enter corresponding mortises or annular grooves I)" Z)? in the respective annuli B B Similarly the latterare provided with tenons Z) o which interlock in niortises b 1), formed in the intermediate annulus B For locking the sections of theinnershell togetherlongitudinally the annulus B may be provided with an internal annular recess b whose edges engage with the shoulders a a on the annuli A A of the inner shell and lock the same securely together.

In Fig. 4: I have represented a modified form of construction, which will be seen to differ mainly from that shown in Fig. 3 in a substitution of the construction of the inner for that of the outer shell and that of the outer for that of the inner shell. The method of interlocking the shells may be similar to that described in relation to the construction shown in Fig. 3.

A door may be secured to the safe in any suitable manner.

lVhat I claim as new, and desire to secure by Letters Patent, is-

A safe comprising an inner cylindrical shell and an outer cylindrical shell, the adjacent surfaces of the shells being provided with en- In testimony whereof I have signed my name to this specification in the presence of [0 two subscribing Witnesses.
